A wheeze is a clinical symptom of a continuous, coarse, whistling sound produced in the respiratory airways during breathing. [1] For wheezes to occur, part of the respiratory tree must be narrowed or obstructed (for example narrowing of the lower respiratory tract in an asthmatic attack), or airflow velocity within the respiratory tree must be heightened.
Asthma is a common pulmonary condition defined by chronic inflammation of respiratory tubes, tightening of respiratory smooth muscle, and episodes of bronchoconstriction. [1] The Centers for Disease Control and Prevention estimate that 1 in 11 children and 1 in 12 adults have asthma in the United States of America. [1]
The wheezing is most often when breathing out. [109] While these are the primary symptoms of asthma, [110] some people present primarily with coughing, and in severe cases, air motion may be significantly impaired such that no wheezing is heard. [108] In children, chest pain is often present. [111]
A common genetic cause is cystic fibrosis, which affects chloride ion transport. [28] Another genetic cause is primary ciliary dyskinesia, a rare disorder that leads to immotility of cilia and can lead to situs inversus. [52] When situs inversus is accompanied by chronic sinusitis and bronchiectasis, this is known as Kartagener's syndrome. [53]
A PCP will ask questions in regards to symptoms and breathing; they will also ask if fatigue or wheezing has been experienced when breathing in or out; and also test using a peak expiratory flow and an oxygen saturation. Status asthmaticus can be misdiagnosed when wheezing occurs from an acute cause other than asthma. Some of these alternative ...
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds. [2]
It presents with a hyperinflated chest, expiratory wheeze and low oxygen. [2] Severe pneumonia is most common in very young children age three to 18 months and presents with sudden illness, ongoing cough, high fever, shortness of breath and a fast rate of breathing. [2] There are frequently wheezes and crackles on breathing in and out. [2]
The underlying cause of this type of bronchoconstriction appear to be the large volume of cool, dry air inhaled during strenuous exercise. The condition appears to improve when the air inhaled is more fully humidified and closer to body temperature. This specific condition, in the general population, can vary between 7 and 20 percent.
